Introduce CONFIG_PHYS_64BIT on ARM to deal with 32 bit ARM platforms with large physical addresses. This is inspired from commit e99ccb488181d0 ("Introduce phys_size_t and move phys_addr_t into asm/types.h") done on powerpc. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> --- - This is needed for platforms like TI's DRA7 which support memory upto 4GB arch/arm/include/asm/io.h | 4 ++-- arch/arm/include/asm/types.h | 5 +++++ 2 files changed, 7 insertions(+), 2 deletions(-)
